The popularity of smartphones and the demand for mobile payments have accelerated the rapid development of biometrics for mobile devices. At this stage, fingerprint recognition is the mainstream technology, but the current technology can only achieve single-finger and fixed-region fingerprint recognition. Innolux focuses on the development of an embedded full-screen multi-finger fingerprint sensing liquid crystal display, the next generation fingerprint recognition technology, directly integrating the light sensor into the LCD array substrate, without the need for additional camera modules and to realize the function of on-screen fingerprint recognition. This display module, with fingerprint recognition, display, and touch functions, realizes a thin and nearly 100% full screen, large-area multi-finger sensing function, and is more security, better user experience and low cost.
